View 2 Replies View RelatedI'd like to use an existing sqlite3 database created outside of the phone, on a computer reachable by Wifi. I know how to download the file using Socket. The problem I see is that android.database.sqlite classes access databases only in /data/data/<package_name>/databases and it does not seem to be possible to write files directly in there. Is there a way to write a file in /data/data/<package_name>/ databases or ask the android.database.sqlite classes to read a database from another place?

View 1 Replies View RelatedI have this database file under the usual databases folder and a bunch of tables inside it. Please note that I don't want to retrieve under the command line. I know I can use the ".tables" command. I want to retrieve a list of all tables in it, using code, so that I can execute some specific algorithms on each of them. Also, I didn't find any questions with this problem on Android, so please forgive me if there is any. I was wondering if there is any function I can use under Databases, but I didn't find any either.

View 2 Replies View RelatedI'm using a SQLite database to store information on players and their teams using android. I've got it working so that all the players I've created will show up when ever I start my program, so the database is working. So far, so good. However, whenever I try to retrieve the rowId of a player from the database, it always gives me 0 back. This surprises me in itself, since I'd think I'd get an error if I wasn't accessing it from the cursor correctly, but instead it gives me 0. After debugging for a while, I realized that the Player object (not in database) also wasn't saving the id correctly, although it was finding a value for it. This was corrected when I set the id after creating the object, although it seems I would be able to set it in the creation statement itself. Curiouser and curiouser. Code...
View 1 Replies View RelatedI need to store an retrieve a vector of an unknown number of objects in an android sqlite database. Essentially, the setup is this: I am developing a task management app, where the user can add as many notes as they like to their tasks. My current setup uses one database, with one row per task. This presents a problem when I need to associate multiple notes and their associated information with one task. I can see two approaches: try to store an array of notes or a vector or something as a BLOB in the task's row, or have another notes database in which each row contains a note and it's info, as well the id of the task which the note belongs to. This seems a little easier to implement, as all I would have to do to retrieve the data would be to get a cursor of all notes matching a particular id and then iterate through that to display them to the user. However, it seems a little inefficient to have a whole new database just for notes, and it makes syncing and deleting notes a little more difficult as well. What do you think? Is it worth it to have a separate notes database? Should I use a BLOB or go for the separate database? If a BLOB, are there any good tutorials out there for storing and retrieving objects as BLOBs?
View 2 Replies View RelatedMy GNex took a baseball to the screen; the screen is shattered and unresponsive, but the phone will power on and I can see the file structure if I connect via USB to my PC. I've retrieved all the files and photos that I want to save from the phone by copying to the PC, but not the text messages. I had a backup for the text messages, but it's gone (different story for another time). So I've been searching for a way to retrieve these text messages that can be executed entirely from the PC side, since I have no way of installing an app on the phone. I'd either like to be able to copy the SMS database to a new phone via PC, or dump it into some sort of manageable text format.
From the searches I've done, it seems like I might be able to do this using some sort of developer's code; (i.e., Install this program, plug in the phone, enter these lines of code, etc.)
The phone is stock (not rooted), and was just recently updated to ICS 4.0.4 (?)
Samsung says they can "fix" the phone for $160+, but that they won't be able to save any of the data since the phone isn't navigable (I assume they'll just send a replacement).

View 3 Replies View RelatedI am building an app that can transfer a photo and bundle data to another persons phone that has the app.
The person would be close by, basically face to face.
In a perfect world I would like the process of file transfer to be less than 3 steps but I think that would be too much to ask for.
I am trying to figure out ways to do it but I keep coming up with blanks for every way I was thinking.
1. Bluetooth (Easier to code, more steps for the user)
2. NFC (How to implement and test)
3. Wifi Direct (Still has steps but less than Bluetooth, just learned about it today so I am new to it)
4. Connect to a Server (Make a server and connect devices)
5. HTTP (Make a temporary server on your phone?)

How to retrieve data from two tables via the ContentProvider way? I.E. the database of Calendar application, include many tables including Events and Deleted, and some others. I want to retrive records in Events table, whose _sync_id field is also in Deleted table. Usually, we write a SQL sentence like: select (all fields in Events) from Events as e, Deleted as d where e._sync_id = d._sync_id or select * rom Events as e where e._sync_id in select _sync_id from Deleted etc. But, how can I accomplish it in the ContentProvider way? I saw ContentProvider.query take a Uri as the first parameter, but pity that I don't know how to build one that could fulfill my purpose.
